The invention relates to new benzoylurea compounds of the general formula <IMAGE> wherein R1 is a halogen atom, R2 is a hydrogen atom or a halogen atom, R3 is a hydrogen atom or represents 1 or 2 substituents which are selected from the group consisting of chlorine, methyl and trifluoromethyl, R4 is a hydrogen atom, an alkyl group having 1-6 carbon atoms or a cycloalkyl group having 3-6 carbon atoms, R5 is a hydrogen atom or an alkyl group having 1-4 carbon atoms, and A is a phenyl group or a heteroaryl group having 1 or 2 nitrogen atoms, which groups may be substituted with 1-3 substituents which are selected from the group consisting of halogen, and alkyl, alkoxy, haloalkyl and haloalkoxy having 1-4 carbon atoms. The compounds have an insecticidal and acaricidal activity. After having been processed to compositions, the compounds may be used for control of insects and/or mites in a dosage from 1 to 5000 g of active substance per hectare. In addition the compounds have an anti-tumor activity and may be used in pharmaceutical compositions. |
